where else is sound deadener found other than the trunk area? jw if rickdogg or someone would know, i dont realy want to strip my car to no avail.....thanks

 

how much does the big chunck of sheet metal behind the seats, with the rear speakers and glove box weight? i've seen a few take it out but never any info about it.

 

There is a lot underneath your seats, under the center console, and also under the portion where your feet rest

 

yay! you answered, thanks....i assumed there would be some there, but i didnt want to take everythign out and be sad that i was wrong...and when ppl said there was around 10lbs of it i was doubtfull that the rear was 10lbs alone since i only got a few pounds if even

 

I heard about a weight that can just be removed somewhere around the engine or in the front of the car, it is about 20kg or something like that, anyone know what i am talking about, i forgot but i would like to pull it out.

 

^^ the i forgot what its called but maybe its it...the front bumper brace thing? or replacing the battery? 20 kg is alot pf weight...

 

I know it's been mentioned before, but there really is a pretty big difference in tire weights out there. I was just checking specs on Tirerack and for the same 265/35/18 tire, there was a 5 pound difference between Goodyear (30lb) and Michelin(25lb)!

Bet many give up the search for lowering unsprung weight after they buy their forged wheels. The tires are even more important since they are furthest away from the hub.

 

no, it is some sort of weight. I was looking around yesterday and i think i know what it was, there is a weight on roadsters up front on the drivers side that is there to balance the car i guess...i'm not sure. I am going to get under my car tonight probably and have a look around.

 

+1 on removing the metal box behind the seats? I wonder how hard it is to remove.

Remove your A/C for some nice front end savings along with relocating the battery.

 

I wouldn't do that unless you plan to install a cage. Looks to be a structural element tying the center of the car together.

 

It's easy, just a little bit of cutting.

These guys do custom plexiglass windows including windshield, I'm about to order the sides and quarter (already have the hatch done).

Huh? since when is a little bit of paper thin sheet metal "a structural element" ?

 

hmmmmm, very interesting....i wonder what the cons are of having the thinnest plexi all around.

 

When it's boxed. Take a look at the construction of the rear strut "bar" it's built the same way.

I've seen this same technique used to strengthen verts since there is nothing else to tie the b-pillars together. You'd be hard pressed to tell, I'm sure, since the coupe has a roof.

Let us know how much it weighs when you remove.

 

I wouldn't run the 1/8" it's a little too flimsy for my taste. I ordered the 3/16" which is the minimum requirement for SCCA. Weight difference is actually minimal, most of the savings on mine will come from the carbon doors without window motors, locks, door panel, etc..

I've already removed the rear "speaker box" and I guarantee you on the coupe it is nothing like the rear strut brace. You actually don't save much weight by removing it though, it's mostly just to clean up the look of the car and to make more room for a better roll hoop mounting location.

 

^^^^^There is a vid of a d1 supra going down a back straight and the front lexan window is caving in....i'll find it.

the carbon fiber doors save like 60 pounds a piece...hatch saves 45 pounds-ish..havent heard anything on the hoods...with all the stuff you said id be more like 250 pounds...& gas? we're talking curb weight here right?

 

Has anyone put in a carbon hatch but kept the rear wiper? Or do most of the cf hatches not accomodate the wiper mechanics?

I think that's a compromise I'm going to have to strike with my wife if it's possible.
